Direct cod liver oil evidence
• Respiratory/COVID prevention — negative. The largest dedicated RCT, a quadruple-blinded trial of 34,601 Norwegian adults, found cod liver oil (5 mL/day) did not reduce SARS-CoV-2 infection, serious COVID-19, or other acute respiratory infections versus placebo. This is the strongest direct trial and it is null.
• Type 1 diabetes — observational only. A Norwegian population-based case-control study found cod liver oil use in the first year of life was associated with lower risk of childhood-onset type 1 diabetes (adjusted OR 0.74, 95% CI 0.56–0.99), hypothesized to reflect anti-inflammatory n-3 effects. This is hypothesis-generating, not interventional.
• Pediatric upper respiratory infections — weak. A small cluster-randomized study suggested fewer URI visits with cod liver oil plus a multivitamin, but the design and confounding limit inference.
• Bone mineral density — essentially null. An Icelandic cohort found no meaningful association between lifelong cod liver oil intake and hip BMD in old age; the only benefit was a predictable rise in serum 25(OH)D.
Extrapolated omega-3 evidence (the strongest signals)
• Rheumatoid arthritis has the most consistent (though modest) benefit of any indication. Marine n-3 PUFAs reduce tender joint count, morning stiffness, and NSAID use across systematic reviews, with effect sizes that are small and evidence often low-certainty; anti-inflammatory doses (≥2.7 g/day n-3) exceed what a typical cod liver oil dose delivers. Of note, cod liver oil was historically first used for RA in the 1700s.
• Cardiovascular disease benefit is limited and dose-dependent. The 2020 Cochrane review (86 RCTs, ~163,000 participants) found little or no effect of n-3 supplementation on all-cause or cardiovascular mortality, with at most a slight reduction in coronary events. Any cardioprotective signal (e.g., REDUCE-IT) came from high-dose prescription icosapent ethyl (4 g/day), far above cod liver oil content.
• Vitamin D delivery is the one undisputed physiologic effect: cod liver oil reliably raises serum 25(OH)D in a dose-dependent manner.

Did it disappear after a few sales?
